Quantum dots on vertically aligned gold nanorod monolayer: Plasmon enhanced fluorescence

摘要

CTAB-coated Au nanorods were directly self-assembled into a vertically aligned monolayer with highly uniform hot spots through a simple but robust approach. By coupling with CdSe/ZnS quantum dots, a maximum enhancement of 10.4 is achieved due to: increased excitation transition rate, radiative rate, and coupling efficiency of emission to the far field. © 2014 the Partner Organisations.
